Antarctic sea ice has been above average for 1000 straight days

“IF” the Antarctic ice shelf is
(1) “melting” at such higher rates(never measured nor calculated except as several “gigatons per year based on assumed (never calibrated!) GRACE satellite assumptions) to
(2) dilute the surrounding seawater to
(3) raise the normal salt water ocean freezing point from
(4) -x.xx degrees C (never stated! in these arm-waving excuses)
(5) -y.yy degrees C (also never stated, never measured, never explicitly referenced from experimental results, never calculated based on actual seawater temperatures nor air temperatures over time at various salinities) by
(6) “diluting the ocean water” by “how much” over “how big an area”
when
(7) in fact, the air over the Antarctic continent has been steadily decreasing over the past 30 years
(8) and so the increased melt rate cannot be justified except by assumptions.
Assume Wikipedia is “good enough” for simple chemistry.

“Seawater or salt water is water from a sea or ocean. On average, seawater in the world’s oceans has a salinity of about 3.5% (35 g/L, or 599 mM). This means that every kilogram (roughly one litre by volume) of seawater has approximately 35 grams (1.2 oz) of dissolved salts (predominantly sodium (Na+) and chloride (Cl−) ions). Average density at the surface is 1.025 g/ml. Seawater is denser than both fresh water and pure water (density 1.0 g/ml @ur momisugly 4 °C (39 °F)) because the dissolved salts add mass without contributing significantly to the volume. The freezing point of seawater decreases as salt concentration increases. At typical salinity it freezes at about −2 °C (28 °F).[1] The coldest seawater ever recorded (in a liquid state) was in 2010, in a stream under an Antarctic glacier, and measured −2.6 °C (27.3 °F).[2] Seawater pH is typically limited to a range between 7.5 and 8.4.[3]”

(Odd, isn’t it, that the record LOW freezing point for salt water was recorded in the very dilute runoff water DIRECTLY UNDERNEATH an Antarctic glacier…..)
Also, just the “excess” Antarctic sea ice has been “above normal” as a positive anomaly for 8 years now. The Antarctic sea ice anomaly exceeded 2.05 million sq kilometers of sea ice in June, and has been routinely greater than 1.5 mliion square kilometers this year AT ALL actual areas of sea ice.
Thus, IF the continental ice WAS melting and WAS diluting the seawater and WAS causing the sea water to freeze at higher temperatures (thus creating more sea ice easier) then how do you explain how that sea water was being “diluted” at the same levels when the sea ice is 3.0 Mkm^2 at a distance of 0-50-100 kilometers from shore, as when the edge of the sea ice is 800 – 1000 kilometers from the continental edge with an area of 15.5 to 16.0 Mkm^2?
